If kzalloc returns null then isp1760_ep_alloc_request performs a null pointer deference on req.
Dereference, not "deference".
Shall I send v2 for this stupid typo then?
Definitely, especially as your change log doesn't adequately reflect reality anyway.
No, it doesn't. It calculates the address of the 'isp1760_request::req' instead, there's no dereference per se. I suppose this is a first member of the structure, so this function should work correctly in any case.
Well, for now it's the first member, but can we assume that will apply forever?
I guess so.
As it stands, other *_alloc_request() functions in all the other usb drivers check for the NULL, so this fix just aligns the code with all of these other drivers.
OK. [...] WBR, Sergei -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
